Requiring zero configuration, this plug-and-play T1 extender communicates over voice-grade twisted-pair cabling, enabling you to get more distance with fewer copper pairs.

Extend your T1 circuits beyond their typical reach and get more from your copper cabling. BLACK BOX® T1 Extenders for Copper extend T1s as far as 3.5 miles (5.6 km) and require just a single pair of wires to operate.

Save by making the most of your copper.
With these extenders, you can increase connections from the demarc to equipment in your building, and save money by linking remote PBXs over existing dry copper. If you're a service provider, you can use the extenders to reach a larger subscriber base with less copper and at longer distances—without the need for repeaters!

Plug and play with no user settings required.
Plus, they're easy to set up and use, delivering TDM circuit extension with no configuration. Just take them out of the box, place them on opposite sides of the dry copper, and plug in your T1 or E1 line. The circuit is now ready for communications. Because the two active pins on the extenders' RJ-45 connector are polarity sensitive, you don't even have to worry about which wire is connected to the line interface.

Easy to troubleshoot.
Intuitive LEDs alert you to any possible line or circuit problems. For instance, a solid green Link LED indicates a good end-to-end link, and a solid green Frame LED indicates valid framing on the link.

Save space and rackmount multiple units.
You can also stack and organize your extenders and other equipment in the optional 19" Universal Rackmount Panel (ME330-2, ME330-10; sold seperately). Each slot in the panel operates independently, and the rear side has slots for device power supplies.
